The Cold-side Aluminum Intercooler Pipe with HKS Flange is designed to improve the performance of your Focus ST's turbo by facilitating better airflow from your intercooler while replacing the OEM diverter valve (DV). This kit replaces the restrictive cold-side piping with larger mandrel-bent aluminum tubing for smoother airflow and includes everything you would need to install the BOV.
The mandrel bends allow for smooth air flow and the 4-layer silicone couplers with ultra-resistance fibers offer enhanced tolerance against heat and pressure. High-tension t-bolt clamps are also included in the kit. This pipe features a 1/8th NPT bung for meth injection (comes plugged). The kit also features the CVF Boost Reference Adapter Kit and Block-off Plate for seamless installation.
Designed to install easily with basic hand tools, this Cold-side Aluminum Intercooler Pipe with HKS Flange requires no extra modifications and should only take you about 45 minutes to swap out. Complete with all necessary t-bolt clamps and ultra-resistant 4-ply couplers, this kit allows for a quick install.
This product is designed to fit both the automatic and manual 2013-2018 Ford Focus ST.

    Fit well, no kinks

    Cvfab did an excellent job making a cold side piping kit to use the entire available space, with a flange to mount the HKS bov. I like the feature for meth injection if I so choose to in the future. The silicone couplers appear to be great quality and fit snug with the t-bolt clamps.

    It is pretty difficult to mount the bov to the flange, but I got it done in about 15min (the more expensive lock ring pliers are a must!) Have the HKS bov facing down towards the cold side pipe curve, and the vacuum port facing up towards the intake. Upon installation of the cold side, I'd highly recommend seating the smaller coupler to the intake first with clamp, then install the cold side charge pipe with BOV and vacuum line already attached to it. Trying to figure this part out alone took 30min. Mounting the larger coupler to the cold side pipe and connecting it to the intercooler with clamps is the next difficult process. It will seem impossible but its doable, just be patient and take your time to feel around the coupler to ensure proper placement. In total, with removal of the bottom engine covers, removal of the stock cold side piping, and installing the Cvfab parts took approximately 3hrs.

    The quality of the part seems to be top notch. But what's really above and beyond is the customer service. Very available and very willing to assist in any way. My only issue is they don't include install instructions. Even though install is fairly straight forward, I'm a visual person, so reading and seeing photos of how they intend it to be installed just provides me peace of mind. Other than that, I'd recommend this product, and any product from them... Based on the customer service alone.

    Couldn’t have been better

    This install was no doubt, intimidating. With tons of people saying how difficult this project was and how tight of a space there was, making it seem near impossible. With the help CVFAB offered by sending a video on how to install… made it BEYOND easy to do! It was a tight fit, yes. Everything mounting up perfectly! ZERO fitment issues! Everything worked on the first try!!!
